은 marks 이 앱 as the topic of the sentence: As for this app, ...
That gives the sentence a natural topic-comment structure:
- 이 앱은 = as for this app
- 사용법이 간단해서 설명서를 길게 읽을 필요는 없어 = its usage is simple, so there’s no need to read the manual at length
If you used 이 앱이, the focus would shift more toward this app itself as the subject being identified or contrasted. With 은, the speaker is more naturally talking about the app as the topic under discussion.

- this app’s way of use is simple
